DDM Jacobian files for other chemical mechanisms

Dear CMAQ users,

I’m trying to set up CMAQv5.2 DDM with SAPRC07 mechanism. I found that only cb6r3 has a Jacobian code for DDM compile (jac_cb6r3_ae6nvPOA_aq.F). Could you let me know how to generate the “jac” files for saprc07tc_ae6nvPOA_aq?

Thank you for your time.

That jacobian, saprc07tc_ae6nvPOA_aq, should be the same as the one in the volatile directory (jac_saprc07tc_ae6_aq.F). Please, try to pull it out of there and see it works. If you can’t get to work, post here again, and I can help you with it further. Here is the path where you can find it:

CCTM/src/gas/ebi_saprc07tc_ae6_aq/jac_saprc07tc_ae6_aq.F

Hello,I found jac_cb05tucl_ae6_aq.F was not imperfect when I compile CMAQv5.2_DDM-3D with cb05tucl_ae6_aq mechanism.

Could you help me?
Thank you for your time.

Just delete all “C()”. And it will work. That is what I did when I compiled CMAQ-DDM
